While swearing in Mandarin was quite cute - I didn't much buy it, somehow I dont really see the future of swearing getting anything other than what we would consider totally gross, as everything we use today gets watered down, yet one of the curses they use most oftern from memory was "zaogao" - which roughly has a similar level of serverity to "Oh No!" and litterally translates to "Bad Egg" or "Bad Cake".
I mean chinese is a pretty damn cool language and it just seems unlikely that in some future world where the two major languages basically grew so big they crashed into eachother and became one, that all we would keep from it is their swearwords. off the top of my head I would expect us to more likely take their pronouns cos they're simple and effective. one word for first person, one for second, one for third and a suffix to make them plural. (I understand that this would have made pretty awful tv for an english speaking audience)
